Abstract

Изобретение относится к носителю информации, содержащему метки с ограниченной длиной пробега на дорожке. Длины пробега меток представляют собой биты основного канала, и изменения дополнительного параметра меток представляют собой биты вторичного канала. Не все метки имеют указанные изменения, а только метки, по меньшей мере, заранее определенной длины пробега имеют указанные изменения. Изобретение также относится к устройству кодирования, способу кодирования, устройству декодирования и способу декодирования.Международная заявка была опубликована вместе с отчетом о международном поиске.
